Upset review

One year ago studied the development of desktop applications with PywebView:Python Develops Desktop Apps with PywebVIEW
At that time, it was just a taste, there was no complete implementation, and the time was a bit strange. Recently, there is a time, and then review the process of realizing a complete small application, good, jealousy begins to start ~ Bamboo

Goals

The goal is to implement a single-alone address desktop program, interface and function section to implement Flask and Layui. This content is mainly fascinated by Flask to do web development. You can watch it on your own, PS: write is rotten, no too thin functional implementation, mainly to record the process behind the back and packages.

Technology

flaskProcessing background business
layuiDo the front end (simple and rude and effective, the key is compatible with IE)
sqliteLocal database
pywebviewSet of shells into WinForm
pyinstallerBread into EXE

PywebView plus shell

createmain.pyUsed as an primary entrance to the program:

import webview
from com.application import create_app	# Flask instance factory function

if __name__ == '__main__':
    app = create_app(__name__)
    window = webview.create_window(
        title='Address Book,
        url=app,		# This will automatically start the Web service directly to the URL parameter directly to the URL parameter.
        confirm_close=True		#      
    )
    # Customize the Chinese content of the prompt
    cn = {
        'global.quitConfirmation': u'confirm to close?'
    }
    webview.start(localization=cn, gui='mshtml')

Here is explained herewebview.create_windowFunction parametersurl=The back is directly incoming that the instantiated Flask object, the comparison of the official documentation is detailed:

url - URL to load. If the URL does not have a protocol prefix, it is resolved as a path relative to the application entry point. Alternatively a WSGI server object can be passed to start a local web server.

gui='mshtml'Specifies that IE is rendered, the advantage is to eat WIN7 to Win10 all platforms, it is necessary to pay attention to the use of old a little web front-end technology. If the target client is Win10, you can do this parameter, it will automatically match according to the order. Browser rendering engine, priority use Edge rendering, IE, official description:

On Windows renderer is chosen in the following order: edgechromium, edgehtml, mshtml. mshtml is the only renderer that is guaranteed to be available on any system.

Running directly heremain.pyYou can run out:

Pyinstaller package

pyinstallerVersion> = 3.6 After packaging, it becomes simple. Automatic hook analysis depends, no need to add DLL dynamic libraries again.

pyinstaller --onefile --windowed --noconfirm --icon Chat.ico main.py

Parameter explanation:
--onefilePack into a single exe file
--windowedHidden console window
--noconfirmIf there is a DIST file that is packaged, it will be automatically overwritten.
--iconSpecify an EXE icon .ico file

Create under the project path after packagingdistFolder, this time you need manualtemplatesFolders and SQLite database files are copied to the same path to EXE

Try to use it--add-dataPackage the Templates and SQLite data files, find that you can't, run the error, you can't find the template and database files.

Double-click the EXE file to run normally
